UMS 115-9 radial

Postby Stuart Atwill » May 25th, 2025, 2:57 pm

The above engine for the second time a bolt holding the cylinder body to the crankcase has sheared. The first time I was able after much effort to remove and replace the bolt. This time it won't budge and the extraction tool has snapped off inside the bolt. Can anyone fix this for me ? It's M3 size bolt.
